SOLE-PREPARING MACHINE.

SPECIFICATION forming part of Letters Patent No. 651,042, dated June 5,1900. Application filed September 1OJ 1897. Serial No. 651,162. (N0 model.)

vented a' certain new and Improved Machine for Preparing Soles for Boot and Shoe Manufacture, of which the following is a specification.

Thisinventionhas forits object an improved machine for so preparing boot and shoe soles that when the uppers are sewed to the soles a close and practically water-tight joint will be obtained. The machine is intended to produce near the edge of the sole and at any desired distance therefrom a raised portion, forming a rib, to which the upper may be subsequently sewed. By reason of this raised portion which we obtain by means of our machine the upper is not sewed flat to the sole, but vertically against the raised rib.

To make the following description as clear as possible,we have represented our improved machine in the accompanying drawings.

Figure 1 is a side elevation of the improved machine. Fig. 2 is a plan view, and Fig. 3 is an end view,of the same. Fig.4 is an enlarged view of the operating parts of the machine with a sole under treatment. Fig. 5 is a partial plan view of the machine, certain parts being removed to bring into View underlying portions of the machine. Fig. 6 is a partial end view, portions of the mechanism being removed to render more clear the constructions of the remaining parts. Fig. 7 is a detached view of the mechanism for operating the driver. Fig. 8 shows a leather sole, and Fig. 9 a felt sole, after passing through the machine.

Mounted in hearings in the frame A is the driving shaft H of the machine, which receives'its movement from hand or other'motive power. This shaft H has keyed to it at its left-hand extremity a coned roller T, having a slightly-swelled portion or bead at t. This roller T serves to support the sole during the operation of moldingthe rib which is to receive the stitches and to impart a traversing'motion to the sole through the machine.

In front of 'thcTco'ned roller T (see Fig. 1)

is an adjustable support Q for guiding the :sole to the roller. This support Q is secured to the frame A by a clamping-screw g, which passes through an elongated hole q in the supportQ and enters a tapped hole in the frame.

Keyed to the shaft H is a conical-toothed wheel I,which engages with a similar conicaltoothed wheel K, keyed on the end of a shaft G, which has its hearings in a rocking frame B. This shaft G lies, when in its acting position, at an angle of some thirty degrees, or thereabout, to the horizontal shaft H for the purpose to be presently explained. The shaft G has fixed upon its left-hand end (see Fig. 1) a pressing-roller G, formed with two annular ribs, the outer one of which is milled to take a good hold of the work. This roller G, with the roller T, assists in molding the sole and feeding it forward while under treatm em.

Upon the shaft G is keyed a bevel-wheel L, which engages with bevel-wheel M, carried by a short vertical shaft M. On this shaft M is also keyed a spur-wheel N. This wheel N engages with the wheel 0 on a shaft 0, which carries at its upper end a block F, fitted with a crank-pin F. This crank-pin is adjustable in a radial groove in the block by means of a traversing screw it. (See Figs. '5 and 7 E is a square-ended rod formed with an eye which fits over the crank-pin F and is secured by a nut F By this connection of the rod E with the crank-pin it will at each rotation of the wheel 0 receive a rapid toand-fro movement in the direction of its length and be driven into contact with the sole for the purpose of molding the marginal rib thereon. This rod E,as will be seen hereinafter, constitutes the chief acting part of the machine, and it is controlled in its movements bya radius arm R, pivoted to a lug on the adjustable guide P. (See Fig. 5.)

The rocking frame B, which carries the shaft G, is supported on screwed centers B, projecting inward from the opposite. sides of the frame A, and it receives a tendency to rise from a strong spring S, actuating and underlying a rock-lever R (see Fig. 6) for the purpose of lifting the pressing-roller G sole.

and holding it off the work, as shown in the dotted position at Fig. 4.

Upon the frame A is fulcrumed a hooked lever C, from which depends a rod 0', connected at its lower end to a pedal operated by the foot of the workman. This hooked lever C overlies and bears upon a vertical piece D, carried by the movable frame B. Normally when the workman is not pressing upon the pedal the pressing-roller G of the shaft G will retain the dotted position of Fig.

4; but when the workman presses on the pedal connected to the rod 0 the hooked lever O causes the depression of the roller G and the gripping of the work firmly between it and the roller T.

Having thus described the parts which constitute our improved machine, we will now describe its action; but we would first remark that the work which itis intended to perform is to produce the raised vertical portion or rib indicated on the sole at X, Fig. 5. It is to this raised rib that the edge of the upper after it is made up is sewed either by hand or machinery.

The leather sole to be treated may be slit fora slightdepth on its edge by any appropriate instrument. 'lhis done the workman, using the guide Q, as a point of support, introduces the sole between the roller G and the cone '1, placing it so that the grip of the roller G may gage the finishingmint of the raised rib. At this moment he presses on the pedal, so as to bring the roller G down upon the sole, which is thus tightly gripped between it and the cone 'l. The workman then sets the machine in motion. lonsequent upon the rotation of the gripping-rollers the sole is drawn in and the workman holding it there with his hands guides it while the roller G describes a line around the sole equidistant from its edge, pressing down the leather, so as to mold the inner side of the rib at its base to correspond with the angle formed between the head I. of the conical roller '1 and the end of the pressing-roller G. The exact lateral position of the sole with respect to the feed-rollers is determined by the adjustable guide P, sec'ured to the guiding-support Q. During the feeding forward of the sole under the action of the roller G and the cone T the rod E, which may be termed the rib-former, moves with an oscillating backward-and-forward motion under the influence of its revolving crank-pin and repeatedly and violently strikes the edge of the raised portion of the sole against the inner end of the roller G and molds it into a raised rib. By reason of the oscillatory movement of this rod, caused by its connection with the radius-arm B, it does not strike directly against the rib, but rather tangentially, thus aiding in the feeding of the Under these conditions it will be understood that it is necessary that the rapidity of the oscillatory movement of the rod E shall be such that its end when in contact with the leather shall move forward at the same rate as the feed-r0llers, as otherwise the leather will be torn. Again, as the rod E leaves the sole for a certain period of time to retire it is necessary that its acting end should have a sufficiently-broad surface to strike all points of the raised rib in a uniform manner several times. The rapidity of movement of the rod E depends, naturally, upon the relative proportions of the gears which control the revolution of the crank-pin connected to the rod, and we therefore reserve the right to modify the gears according to the material of which the sole may be made. When the workman after having guided the sole by hand comes to the terminating-point of the coursethat is to say, to the place where the raised rib shall cease-he releases the pedal, the shaft G rises, and he can then easily withdraw the sole from the machine.

The required depth and position of the raised rib to be produced by the machine depend, naturally, upon the mode of attaching the upper to the sole and will vary according to its shape.

Our machine will manufacture soles of felt or leather, as above stated, and the pressure and the form of the roller G and the length of travel of the rod E may vary according to the nature of the material employed. These are the only alterations necessary to suit the work. All other parts remain the same whatever may be the material employed.

As the thickness of the sole under treatment varies, the adjustment of the height of the rod E must also vary. For this purpose the rod is passed through the adjustable guide P, which is capable of being raised or lowered. Furthermore, this guide P by reason of its attachment to the support Q admits of slight lateral adjustment to suit the varying width of the flanged portion of the sole.

In the case of felt soles we do not split the edge first, it being unnecessary to do this to obtain the raised rib; but we heat the roller G and the pushing instrument or rib-former E, so that when the rib is molded the heated pressure causes it to retain its rib or guide line shape.

We disclaim, in a lip-turning machine, the combination, with a reciprocating lip-setting tool, of means to so actuate said tool and to support the work, so as to cause said tool to strike and act upon the lip at the base thereof within the angle formed by the lip and feather of the insole; in a lip-turning machine, the combination, with awork-support, of a reciprocating lip-setting tool movable in a plane inclined to the surface of the worksupport; in a lip-turning machine, the combination, with a reciprocating lip-settin g tool, of clamping means arranged to hold the insole against the action of said tool; in a lipturning machine, the combination, with a reciprocating lip-setting tool, of a presser-foot arranged to hold the insole during the operation of said tool; in a lip-turning machine,
